Document Summary
Research group working with new engery, made mistake, sd-gone. 2 electrons, 2 protons strong nuclear force ties electrons and protons four forces gravity 1 electromagnic forces 10^36 strong nuclear force10^40-50, short ranged, photons weak nuclear force the cork model. Half life- amount of time for half of atoms to become something else. Uranium-235 is used to make bombs very rare to find, can do something to change half life, very stable half life is 700 billion years under spontaneous decay cause decay by smacking it with neutron. Dangerous when- electron is moved away from an atom-ioniation radiation. About 1000x stronger than bombs from cold war. Dense energy sources and what to do with them. Found out way to make bomb and other side prob knows as well. Difficult fuel to attain-needs to be 90% to become bomb grade, engery 5%, natural is . 07. Once you get from . 07 to 5% its easy to get to 90%
